Yesterday, I released the first open source version of RefactorWiki, a Java-component and accompanying J2EE-webmodule to rename (move) pages and their respective links within a Wiki. Currently the following php-based Wiki-engines are supported: WackoWiki v4, WikkaWiki v1.1.6.0.

you should be able to figure our what's happening. Don't hesitate if you have any questions.

As far as the choice for Java; I'm better at it than at PHP, Java offers various tools to greatly ease development; furthermore; when implementing the refactor-action in php, you risk that a timeout is hit when refactoring multiple pages.

I'll soon post instructions on how to integrate PHP and Tomcat (J2EE WebContainer) in Apache.
